7 Claims. (01. 155-424) The present invention relates to desks,primarily though not exclusively to school desks.

'It is' an object of the invention to provide a school desk primarilyfor the younger child which serves not only as a desk but also asawritingsurface-such, for example, as a blackboard.

' The invention comprises broadly a chair and idesk'assembly whichincludesia frame adapted to carry 'a chair and a desk top in suitablerelation thereto, said top being pivotally mounted so that be used asthe upper surface, one side being adapted to serve as a desk surfaceproper and the other side being adapted to serve "as a writing surface,such, for example, as a blackboard.

Conveniently the desk top is provided on one side with a peripheralgroove and on the other sidewith a peripheral ridge. In one form thedesk top may be pressed from sheet metal, the

groove and ridge being formed in the pressing operation.

be described with refer- Figurel is a perspective view of a deskconzstructedin accordance with the present invention, and I Figure2 isaside elevation of the desk shown in Figure 1 showing details ofconstruction.

The desk frame is "formed essentially from two tubular- U-shaped membersland 2 provided with flattened bases -3 and 4, respectively, which formthe floor support for the desk. Each of the U- shaped members isprovided with a short leg 5 and a long leg 6. The short legs 5 serve tosupport a chair 1 and the long legs 6 support a desk top 8. To providerigidity to the assembly the two U-shaped members I and 2 are tied by across bar 9 which may also serve as a footrest.

The chair 1 is constructed from an inverted tray portion I which servesas a seat and may be stamped out from sheet metal, a backrest II whichmay comprise a metal pressing and two armrest members l2-|2 which serveto tie the backrest H and seat Ill.

The seat [0 may be welded to the upper ends of the legs or may beslidably mounted on a subframe l3 which is fixedly secured to the legs5-5.

The backrest ll may be connected to the seat portion I0 by bolts as at14 and further connected by the armrests H which are formed from arcuatemetal strips turned at each end to engage pins 15 and I6 projecting fromthe seat I0 and backrest II respectively. 7

The desk top 8 is formed from a metal pressing and is provided on oneside with a peripheral proper and vice versa.

recess or groove I! which provides on the opposite side a peripheralridge. The side shown uppermost in the drawings is provided with ablackened surfaceso that it may act as a blackboard, the

gr0ove l1 serving as a tray for the chalks or other writing implements.The desk top 8 is rotatably mounted between the legs 6, by means'of apair of rotary clamps l8. Each clamp comprises a pair of disc memberseach provided with radial serrations or teeth, one disc member'beingsecured to the desk top and the other disc member being secured to thetop or the leg 6. The disc secured to the desk top carries a centralspindle which passes through the disc secured to the leg top and isthreaded to carry a thumb screw i9. By tightening or loosening the thumbscrew IS on each rotary clamp the desk top may be locked into anyangular position with either side of the desk top uppermost. I

When'the side of the desk top opposite to the blackboard is uppermostthe ridge serves to retain books or other articles on the desk top.

The desk top preferably is not centrally pivoted but is pivoted 01fcentre so as to bring one side ofthe desk top closer to the chair thanthe other.

Thus it may be found more convenient to have .;By making thechain-desktop and tie rod 9 :detachable it is possible tov pack the disassembleddesk into a comparatively fiat form. The chair itself may bedisassembled by removing the armrests and the bolts securing it to theseat portion.

What I claim is:

1. A combination chair and desk assembly comprising a pair of spacedU-shaped tubular members each terminating at one end in an upstandingshort leg and at the other end in an upstanding long leg, a desk top inthe form of a substantially flat metal stamping eccentrically pivotallyconnected between and supported only by the tops of the upstanding longlegs, said desk top being provided with a concave-convex channel aroundits edges forming a peripheral groove on one side and a peripheral ridgeon the other side, cooperating clamping means carried at the upper endsof said long legs and on the ends of said desk top for retaining saiddesk top in any angular position with either side uppermost, a combinedcross tie-rod and foot-rest connecting said U-shaped members adjacentthe lower ends of said long legs and a seat member connected to andsupported only by the tops of the upstanding short 3 legs, the saidtubular members being flattened between the short and long legs toprovide a floor support.

2. A combination chair and desk assembly comprising a pair of spacedtubular U'-shaped members each of which terminates in an upstandingshort and an upstanding long leg, a desk top connecting the ends of thelong legs and a chair connecting the ends of the short legs, said desktop and chair constituting the only connections between said legsadjacent the ends thereof, said short legs being slanted forwardly at anacute angle to the plane of the chair seat to provide a resilientsupport therefor.

3. A combination chair and desk assembly comprising a pair of spacedtubular U-shaped members each of which terminates in an upstanding shortand an upstanding long leg, a desk top connecting the ends of the longlegs and a chair connecting the ends of the short legs, said desk topand chair constituting the only connecting members between said legsadjacent the ends thereof, said short legs being slanted forwardly andsaid upstanding long legs being slanted backwardly.

4, A combination chair and desk assembly comprising a pair of spacedgenerally U-shaped, tubular members, each terminating at one end in anupstanding short leg and at the other end in an upstanding long leg, adesk top in the form of a substantially flat metal stamping pivotallyand ansupstanding long leg at the other end, a chair supported only uponand connecting the short 'legs, a desk top supported only upon andforming the only connection between the tops of the long legs, and across tie-rod connecting said long legs adjacent the lower ends thereof,said cross tie-rod being usable as a foot rest by a personsitting in thchair, said desk top, said chair and'rsaid tie-rod comprising the onlyconnections between said tubular members.

6. A combination chair and desk assembly comprising a pair of laterallyspaced, U-shaped onepiece tubular members, each said member including agenerally horizontal floor-engaging portion with an upstanding short legat one end and an upstanding long leg at the other end, said legs beingslanted toward one another, a chair supported only upon and connectingthe short legs, a desk top supported only upon and forming the ,onlyconnection between the tops of the long legs, and a cross tie-rodconnecting said long legs adjacent the lower ends thereof, said crosstiesupported only upon and forming the only connection between the topsof the upstanding long legs, cooperating clamping means carried. at theupper ends of said long legs and on the ends of i said desk top forretaining said desk top against pivoted movement, a crosstie rodconnecting the long legs of said U-shaped members adjacent the lowerends thereof, said rod being usable .as a

foot rest, and a, chair supported only upon and,

connecting the upstanding short legs, the said tubular members beingflattened between the short and long legs to provide floor-engagingportions, said desk top, said tie-rod and. said chair comprising theonly connections between said tie-rod comprising the only connectionsbetween said tubular members.

7. A combination chair and desk assembly in accordance with claim 3including pivotal con- "nections between the ends of th long legs andthe desk top, said desk top being rotatable by means of said connectionsto selectively present the opposite sides thereof at the use positionand clamping means cooperatively associated with said pivotal connectionto retain'the desk top in any desired angular position.
